WHEEL.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed September 23, 1912. Serial No. 721,795.

To all whom it may concern:

Be it known that I, AUSTIN CURzoN 'LAMBE, a subject of the King of GreatBritain and a Canadian citizen, residing at 233 Wright avenue, in thecity of Toronto, in the county of York, in the Province of Ontario,Dominion of Canada, have invented certain new and useful Improvements inWheels, of which the following is a. specification.

This invention relates to wheels and more particularly to that type inwhich wedges are used for tightening up the spokes.

The main object of my invention is to provide a simple and effectivemeans whereby the tightening up of the wheels is brought about withoutthe necessity of reducing the felly and retiring the wheel. while at thesame time enabling said wheels to be readily taken to pieces, easilyrepaired, and reassembled with facility.

' A further object of my invention is to provide means whereby thespokes may be firmly adjusted and locked against either lateral orlongitudinal displacement so long as the several parts of the wheel areassem- I bled.

A still further object is to provide means whereby in the event ofinjury or breakage to any of the parts, the injured or broken part canbe expeditiously removed and replaced by a perfected part and the wholeeasily and rapidly reassembled.

With these and other objects in view, as will be apparent from thefollowing description, the invention consists essentially in the novelconstruction, arrangement and combi nation of parts hereinafter fullydescribed and pointed out by the appended claims.

The accompanying sheet of drawings is in illustration of my invention:Figure 1, being a fragmentary side elevation of the nave of a wheelembodying my improvements, the lower part being broken away or insection for the sake of clearness. Fig. 2, is a similar part sectionalplan of the same.

Like characters of reference desi ate the same parts in both figures ofthe rawings.

According to the form of my invention illustrated, 1, is the wheel hubwith which is integrally formed the inner flange 2; and 3, is the outeror loose flange.

The shank portions 4, 4, of each spoke are made of a width to fit snuglybetween the flanges 2, 3, and they are formed at one side thereof with aflat side 5, which is angularly disposed with relation to the axis ofthe spoke, and at the opposite side with a radially flat obliquelydisposed side 6.

7, 7, are wedges of appropriate material which are made with a centralvertical en largement 8, of a cross section to bed snugly intocorrespondingly shaped grooves or channels provided for the purpose inthe adj acent faces of each alternate pair of shank ends 4, 4. Axiallyof the enlargements 8, there is provided a hole through which passes abolt 9, furnished with a square head 10, that fits snugly into acorrespondingly shaped recess provided for its reception at the lower.or inner end of each wedge. The outer end of each bolt- 9, is screwthreaded to receive a nut 11, and washer 12..

13, 13, are bridge pieces which are of such a length to lie across thehub parallel with its axis and they rest upon the circumferential edgesof the aforesaid flanges 2, 3; and it will thus be seen that bytightening up the nuts 11, 11, the wedges 7, 7, are drawn nearer to thebridges, whereas by slackening said nuts the wedges may be retractedtherefrom.

14, 14, are axial wedges adapted to fit be tween the alternate obliquelyand reversely disposed faces 6, 6, of the spoke ends 4, 4; and saidwedges are bored and threaded to receive correspondingly threaded screwbolts 15, 15, furnished with heads 16, 16, arranged on the outside ofthe wheel, and lock nuts -17, 17, on the inner face thereof. These axialwedges 14, 14, may be alternately reversed, that is to say, the thinnerend of one wedge may adjoin the outer flange 3, and those on each sidethereof face the inner flange 2, the faces of the spoke ends beingcorrespondingly shaped to conform therewith. Furthermore said axialwedges 14, 14, may be fashioned with enlargements as described withreference to the aforesaid wedges 7, 7, as will be self evident to thoseskilled in the art to which my invention appertains.

It is to be particularly noted that by adopting the arrangement andcombination of parts shown and described, I am able to produce a muchmore rigid and reliable wheel than hereto-fore while the rim or tire ismaintained always in dead truth with relation to the hub.

From the foregoing description and accompanying drawings it will beclearly seen that by my invention I provide an exceedingly simple,strong and durable wheel, while all the parts can be made to a standardgage or templet and thereby rendered readily interchangeable.Furthermore in case of damage or injury to any particular formed at itsinner end and at one side with a flat face lying at an angle withrelation to the of the spoke and upon its opposite side with an obliqueface angularly disposed with relation to the wheel axis, a pair of.spaced flanges between which the inner ends of the spokes lie, wedgesdisposed between. "the-said flat faces of'the spokes adapted forindividual radial adjustment, and wedges arranged between the obliquefaces adapted for individual adjustment parallel to the axisof thewheel, substantially as set forth for the purpose specified.

2. In a wheel the combination with a plurality of spokes, each of saidspokes being formed at its inner end and at one side with a flat "facelying at an angle with relation to the axis of the spoke, and upon itsopposite side with anoblique face angularly disposed with relation tothe wheel axis, a pair of spaced flanges between which the inner ends ofthe spokes lie, wedges disposed between the/said flat faces of thespokes adapted for individual radial adjustment, and wedges arrangedbetween the oblique faces alternately in reverse directions said latterwedges being adapted fo'rindividual adjustment parallel to the axis ofthe wheel, subiitantially as set forth for the purpose speci- 8. In awheel the combination with a plurality of spokes, each of said spokesbeing formed at its inner end and at one side with a flat face lying atan angle with relation to the axis of the spoke, and upon its oppositeside with an oblique face angularly disposed with relation to the wheelaxis, a pair of spaced flanges between which the inner ends of thespokes lie, wedges disposed between the said flat faces of the spokes,means supported from said flanges for drawing said wedges radiallyoutward wedges arranged between the oblique faces, and means for drawingsaid wedges axially outward toward the outer flange substantially as described and shown for the purpose specified.

4:; In a wheel the combination with a plurality of spokes, each of saidspokes being formed at its inner end and at one side with a flat facelying at an angle with relation to the axis of the spoke, and upon itsopposite side with an oblique face angularly disposed with relation tothe wheel axis, a pair of spaced flanges between which the inner ends ofthe spokes lie, wedges disposed between the said flat face of thespokes, means supported from said flanges for drawing said wedgesradially outward, wed es capable of individual movement arranged betweenthe oblique faces, means for drawing each of said wedges transversely tothe wheel and toward one of said flanges, said last named wedgesbeingarranged alternately in reverse directions, and said transverselyadjustable wedges being alternately disposed with relation to saidradially movable wedges.

Signed at Hamilton, Ontario, Canada, this 18th day of September, A. D.1912.
